WINDOW-VENTILATOR.

Specification of Letters Patent.

Patented Mane, on.

Application filed October 19, 1915. Serial N0.'56,7 74.

To all whom it may concern:

Be it known that I, J OHN C. Soorr, residing on Lexington Pike, Kentoncounty, State of Kentucky, have invented certain new and usefulImprovements in Window-Ventilators, of which the following is a clear,full, and exact description, attention being called to the drawing whichaccompanies this application and forms a part thereof.

This invention relates to ventilators adapted to be set in openingswhich are provided in walls inclosing dwelling places for the purpose ofpermitting passage of air.

The intended function of ventilators so used consists of preventingingress of rain, of insects, etc., and to prevent direct and strongdrafts of air. There are ventilators of this kind which are used inconnection with windows and set into an open space obtained by thepartial opening of one of the sashes.

My invention concerns a ventilator of this type and consists of theconstruction of the same as hereinafter described and claimed and asillustrated in the accompanying drawing in which:

Figure 1. shows my ventilator as it appears from the outside of thewindow.

Fig. 2. shows it as it appears from the inside of the window and withparts broken away.

Fig. 3. is a similar view partly in section and shows more of the partsremoved.

Fig. 4. shows the device in vertical crosssection and at enlarged scale.

Fig. 5. shows the left upright part of the window-frame in horizontalsection, taken through the ventilator.

Fig. 6. shows the right part of the win dow-frame in similar section.

Fig. 7. shows a. detail of the construction.

In the drawing numeral 9 indicates the sill and 1010 shows portions ofthe up right parts of the window-frame which contain the sash-ways, oneon each side of the parting strips 1111. 12 indicates as much as isshown of the lower or inner sash. The upper or outer sash does notappear. The

' ventilator consists of an inner and of an outer part which parts areconnected to each other. The inner part is in form of a flat sheet-metalmember 13 which is multi-perforated to permit passage of air. The outerpart consists of a series of ridges and forms a shedding member 14 theobject of which is to prevent rain from entering through the openings inventilating member 13. Interference with the passage of air is preventedby openings in the horizontal part of the ridges of member 14. The loweredge 15 of member 13 is turned around and lapped over the lower edge ofmember 14.

This ventilator is intended to be used across the lower part of awindow-opening to admit air below the lower sash after the same ispartly raised as it appears in the drawing and is best shown in Fig. 4.It is fitted with its ends between the parting strips, see Figs. 5 and6, and is held in position by flanges 16 on said strips. The at tachmentis made by poising the ventilator so that its lower edge is above theupper end of flanges 16, after which it is lowered so that said flangesare received in the space between the two members of the ventilator asshown in Figs. 5 and 6. To admit these flanges, portions at each of thelower (forners of member 13 are removed as shown at 22 in Fig. 3, sothat its overturned lower edge 15 does notextend to the ends of theventilator and leaves the space between members 18 and 14 open at theirends as shown in Fig. 1.

The ventilator is locked in place by slides 17 adjustably positioned inthe space between its members 13 and 14, one at each of its ends. Theseslides have a movement in this space to or from flanges 16 and whenmoved outwardly toward these flanges, a hook 18 at the lower outercorner of each slide passes under the lower edge of flanges 16 thuslocking the ventilator so as to prevent it from being lifted out.

Fig. 3 at the right side of the window shows this slide in the unlockedposition, and at the left side, it is shown in looking position. Figs. 5and 6 show the slides in corresponding positions. The slides aremanipulated for the purpose by means of a suitable implement or key theend of which is inserted into openings 19, one being provided in eachslide. Access to these openings is made possible by provision of slots21. Numeral 23 indicates a hingedly attached deflector positionedinwardly from frame on each side thereof. The engagement is with atubular bead 25 at the upper edge are slidable in their bearings 32 sothat when moved away from the deflector this latter becomes disengagedand may be re moved whenever desirable or necessary for any purpose.

Shields 26 below arms 27 serve to carry out the function of thedeflector at the ends of the same for the purpose of directing the airupwardly.

To prevent movement of the sash from the position to which it has beenadjusted with reference to the ventilator, a suitable looking bolt isprovided which may be mounted in one of arms 27 and is provided with amanipulating knob 29 whereby it may be moved with reference to a socketprovided for it in the saSh frame.

Having described my invention, I claim as new:

1. In a window ventilator adapted to occupy and close the open spacebelow a partly raised sash, the combination of the ventilator consistingof two superposed members, flanges secured to the window-frame andlocking slides contained betweenthe superposed members of the ventilatorat each end thereof and having an endwise sliding adjustment betweenthese members for the purpose of engaging said flanges to lock theventilator in position.

2. In a window ventilator adapted to 00- cupy and close the open spacebelow a partly raised sash, the combination of the ventilator consistingof two superposed member, flanges attached to the window frame andadapted to occupy the space between said superposed members at the endsof the ventilator to hold the same in position and locking slidesprovided between said superposed members of the ventilator at the endsthereof and adapted to engage said flanges to lock the ventilator in itsposition.

In testimony whereof, I hereunto affix my signature in the presence oftwo witnesses.
